What are some potential challenges when creating a PHP script without using MySQL?

One potential challenge when creating a PHP script without using MySQL is the inability to store and retrieve data efficiently. To solve this, you can use alternative data storage methods like flat files or SQLite databases. Another challenge is the lack of built-in security features provided by MySQL, so you'll need to implement your own security measures to prevent SQL injection attacks. 

// Example of using flat files for data storage
$data = "Hello, World!";
$file = 'data.txt';
file_put_contents($file, $data);

// Example of using SQLite database for data storage
$db = new SQLite3('data.db');
$db->exec('CREATE TABLE IF NOT EXISTS data (message TEXT)');
$db->exec("INSERT INTO data (message) VALUES ('Hello, World!')");
